Single-serving disposable container (variants)

ABSTRACT

The group relates to single-serving disposable containers for packaging. A single-serving disposable container is proposed, comprising a front wall of the container and a back wall of the container, which are connected to each other forming an inner sealed cavity designed to contain a granular product with a weight from 1 to 20 g. According to the first variant, in the container, the front and the back walls of the container are made of paper with a density from 18 g/m2 to 90 g/m2 with a laminating layer with a density from 10 g/m2 to 40 g/m2. According to the second variant, in the container, the front and the back walls of the container are made of a polymer film with a thickness from 12 microns to 80 microns. The invention is aimed at the creation of a container, while opening which with one hand a uniform and more accurate extraction of a granular product from the dispensing outlet of the product, located in the bottom part of the container, is ensured.

FIELD OF THE INVENTION

The proposed group of inventions relates to single-serving disposable containers and is intended for packaging, storage, and sale of granular products therein, for example, sugar, salt, soda, powdered products, granulated products, and other comestibles and non-comestibles.

BACKGROUND OF THE INVENTION

The demand for consumer commodities disposable packaging is ubiquitous, especially in food, pharmaceutical industries, field of personal care, and others. Granular products such as salt, sugar, pepper, medicated powders are currently available in individual single-serving containers. Flat containers or bags in the form of packets with three or four welded edges or tubular containers are preferably used for small portion packaging of granular products. These relatively small containers are usually opened by tearing them apart. Therefore, in the probable opening area, the place of the assumed split of the weakened material can be determined, for example, in the form of laser-cut lines, which extend only over a part of the film laminate material thickness. Another probable split location can be, for example, a cut for rupture located in the welded joint. To open the container, normally, it is fixed in two places between the index finger and the thumb of each hand, and opening by tearing is carried out with the differently directed movement of two hands relative to each other. The disadvantage of the known containers is that even if the container is carefully torn, the product comes out during a tearing process and undesirably gets onto the hands and the external environment (table, clothes, etc.). A second disadvantage of the known containers is that additional equipment, which makes cuts or places of material weakening, is required for the production of such containers to facilitate their opening. Also, the design of such containers does not allow to conveniently extract the contents from them with one hand.

Stick-packs “tubulars”, which not all consumers manage to open with one hand, are known. Many people use two hands for this manipulation, tearing a stick in two or ripping off one of its edges. It is possible to extract the contents from such containers by pushing the container between the index and middle fingers of one of the hands, simultaneously pressing with the thumb on the back of the stick, that does not always lead to its correct rupture and often leads to the spilling of the contents after rupturing a stick past a cup of tea, coffee or other drink or dish. The reason for such is the fact that when the stick is opened in this way, a sharp rupture occurs, in fact, the stick bursts, and is not torn, which causes a sharp extraction of its contents under internal pressure and leads to uncontrolled release of the contents. Also, prior art containers are not resistant to external influence. If even a few drops of water get on the surface of the container, it becomes unusable and loses its consumer properties and saleable condition.

It, therefore, follows that there is a problem of designing a single-serving container that has a one-hand opening system and at the same time protecting contents from moisture.

Prior Art

A single-serving container for consumable substances is known from the prior art (Application US20100193515A1, IPC B65D75/46, priority: Jul. 9, 2007) comprising a tubular element wherein opposing internal wall portions at an end of the tubular element are adhered together to maintain the tube in a closed configuration, and are adapted to be separated in order to operate the tube into an open configuration. The best embodiments describe a container for a product that is made of plastic or polypropylene. It is very difficult to recycle such containers after the use of a product, as plastic is not an environmentally friendly material, demands separate recycling with other plastic waste.

A packaging single-serving container for sugar is known (Patent RU188478, IPC B65D 77/08, published on Apr. 15, 2019), comprising an oblong paper packaging-tube, pressed at the ends, having perforation areas, wherein in the middle part of the packaging from the external side of the layer the part-through perforation is performed. The presence of the part-through perforation complicates the manufacturing process, and can also lead to the inadvertent opening of the container, for example, during transportation.

A container for granular material is known (U.S. Pat. No. 3,473,650A, IPC B65D83/06, priority: Jan. 24, 1968), comprising a tubular thin-walled flexible casing, said casing having a length equal to at least four times its width, said casing being filled to at least 85% capacity with said granular material and being sealed at its ends. The disadvantages of this decision are identical to the disadvantages of all known stick-packs.

Technical Problem

DETAILED DESCRIPTION

Additional applicability of the present invention will become evident based on the detailed description provided herein. However, it should be understood that this detailed description and the specific examples given therein, although they indicate preferred variants of the present invention, are added only by way of illustration of the invention since various changes and additions are possible without exceeding the essence and scope of the invention, which will become apparent to those skilled in the art upon reading the detailed description provided herein.

In FIGS. 1-3 as an example is shown, a packaging container 100 (according to the first variant of the invention), which comprises two structural details of paper with a laminating layer: a front wall of the container 101 and a back wall of the container 102.

The connection of structural details to each other along a perimeter is performed by heat pressing or another known method. As a result, a sealed part (cavity) 103 is formed, providing an inner chamber for containing packaged granular product 104. After heat pressing along an entire perimeter of the container, along an upper side 105, lateral sides 106, 107, and in a bottom part 108, a sealed strip 109 is formed, which prevents spontaneous dispensing of the contents from the sealed part 103. In different variants of the invention, the dimensions of the sealed part 103 may be as follows: 2-9 cm in width, 1-6 cm in height.

As shown in FIG. 1 , said single-serving container 100, has an inner sealed cavity 103, generally in the form of an incomplete circle or oval, which is formed by the connection of the front wall of the container 101 and the back wall of the container 102 during the heat pressing process.

In the proposed container, walls 101 and 102 are made of paper with a density from 18 g/m² to 90 g/m² with a laminating layer with a density from 10 g/m² to 40 g/m².

Paper with a density from 40 to 50 g/m², laminated by polyethylene with a density from 10 to 15 g/m² is the optimal choice for the production of disposable single-serving containers, taking into account the optimal properties, including tensile strength, resistance to external influences; has relatively good resistance to water permeability; the resistance of the sealed strip formed as a result of heat pressing to external influences; preservation of the saleable condition and consumer properties; ease of the extraction of the contents by squeezing the container from two lateral sides towards each other with the fingers of one hand.

Paper with a lower density holds its shape badly and is more susceptible to damage during transportation, storage, and use.

Paper with a higher density is economically less profitable because its cost is higher. Also, the production of containers from paper of high density requires the modernization of modern equipment.

Lamination of paper with polyethylene of lower density is practically not carried out by manufacturers, since this does not provide sufficient sealing of the inner sealed part and protection of its contents, and as a result, the contents may be exposed to external factors. A significant increase in the density of the lamination layer is not advisable or justified, and will also lead to a difficult extraction of the contents from the container by squeezing the container from two opposing lateral sides with the fingers of one hand and will increase the cost of production.

In the proposed container, the width of the sealed strip 109 is from 1 to 12 mm, preferably from 3 to 5 mm. The chosen sealed strip width provides optimal resistance of the sealed strip to rupture or accidental damage, ensuring integrity and sealing of the inner sealed part of the single-serving disposable container, as well as providing the possibility of easy extraction of the contents by squeezing the single-serving disposable container from the opposing lateral sides with fingers of one hand.

As shown in FIGS. 1-7 , the upper side 105 of the container is performed straight and wider than the bottom part 108. The dispensing outlet of the product 104 is located on the tapering portion of the bottom part 108. Said constructive design allows easy extraction of the contents of the sealed part 103 of the container to be removed by simultaneous squeezing of the opposing lateral sides 106 and 107 of the wide upper part of the container towards each other with the fingers of one hand (as shown in FIG. 18 ), resulting in the bottom part 108 of the container tears or moves apart in the place of the lower sealed strip 109 and the contents of the container are spilled out vertically downward smoothly and relatively evenly, and the product gets into the chosen place of the dispensing much more accurately.

As shown in the alternative embodiment in FIG. 4 , on the sealed strip 109 in the bottom part 108 a cut 110 can be performed in the lowermost part of the bottom 108 to indicate the dispensing outlet of the product 104. Said realization facilitates the process of the product extraction, and the tearing of the container in the lower part goes faster since the cut weakens the sealed strip strength.

One or both of the structural details of the single-serving disposable container for granular products, entirely or partially, can be made transparent, so that the contents of the container can be seen by the consumer. For example, FIG. 5 shows the container in which one of the walls (the front wall 101) is performed with a transparent insert 112.

FIGS. 6A, 6B, 6C, 6D show the container in which the front wall of the container 101 and the back wall of the container 102 are connected to each other forming the inner sealed cavity 103 with a longitudinal bottom.

FIG. 7 shows the container in which the front wall of the container 101 and the back wall of the container 102 are connected to each other forming the inner sealed cavity 103 in a form of a trapezoid with a narrow bottom.

FIG. 8 shows the container in which the front wall of the container 101 and the back wall of the container 102 are connected to each other forming the inner sealed cavity 103, a top of which is concave towards the bottom.

FIG. 9 shows the container in which the bottom part 108 additionally has a cross detail 111 of the sealed strip 109. Said cross detail 111 is intended to facilitate rupture of the container at its bottom part and the extraction of the contents by squeezing the single-serving disposable container from the opposing lateral sides with the fingers of one hand.

To produce the containers, according to the first variant of the invention, a vertical automatic packaging machine VZ-320 can be used, originally intended for the production of containers with sugar (sticks) of the prior art with a packaging speed, according to the characteristics stated by the manufacturer, equal to 35-70 containers per minute, where the container is filled with granular contents and using a special press mold the sealed strip is formed along an entire perimeter of the container with a width of 3-5 mm and a trimming to intended shape is performed. To produce disposable single-serving containers according to the invention, a special press mold was made, and the packaging machine was reconfigured without changing its structural details. The maximum packaging speed for disposable single-serving containers according to the invention was 60-70 containers per minute. During the experiments, it was possible to easily extract the contents from the received container by simultaneous squeezing of the container in the upper part from the opposing lateral sides with the fingers of one hand towards each other. And the contents of the container have been dispensing vertically downward rapidly and relatively evenly.

In FIGS. 10-12 as an example is shown, of a packaging container 200, which comprises two structural details of plastic film: a front wall of the container 201 and a back wall of the container 202. The connection of structural details to each other along a perimeter is performed by heat pressing or another known method. As a result, a sealed part (cavity) 203 is formed, providing an inner chamber for containing packaged granular product 104. After heat pressing along an entire perimeter of the container, along an upper side 205, lateral sides 206, 207, and in a bottom part 208, a sealed strip 209 is formed, which prevents spontaneous dispensing of the contents from the sealed part 203. In different variants of the invention, the dimensions of the sealed part 203 may be as follows: 2-9 cm in width, 1-6 cm in height.

As shown in FIG. 10 , said single-serving container 200, has an inner sealed cavity 203, generally in the form of an incomplete circle or oval, which is formed by the connection of the front wall of the container 201 and the back wall of the container 202 during the heat pressing process.

In the proposed container, walls 201 and 202 are made of a polymer film with a thickness from 12 microns to 80 microns.

The single-serving container according to the invention is made of a polymer film, for example, biaxially oriented polypropylene film, or oriented polypropylene film, or non-oriented polypropylene film.

The choice of the kind and type of polymer film is carried out according to the requirements for the packaging of a particular granular product. The use of the polymer film, in particular, biaxially oriented polypropylene film, allows protecting contents of the disposable single-serving container for sugar from moisture influence and penetration of foreign odors, extending shelf life, resulting in that the contents can be stored usable for much longer compared to paper packaging.

The use of a film with a thickness of 20-35 microns is sufficient to ensure the protection of the contents of the disposable single-serving container, preservation of the saleable condition. Also, polymer films of this thickness are the most common on the market of packaging materials for comestibles, therefore, market prices for such are optimal considering the high competition between film producers among themselves, which makes its use economically profitable and convenient.

A polymer film with a higher density is economically less profitable because its cost is higher. Also, the production of containers from films of high density requires the modernization of modern equipment.

In the proposed container, the width of the sealed strip 209 is from 1 to 12 mm, preferably from 3 to 5 mm. Said sealed strip width provides optimal resistance of the sealed strip to rupture or accidental damage, ensuring integrity and sealing of the inner sealed part of the single-serving disposable container, as well as providing the possibility of easy extraction of the contents by squeezing the single-serving disposable container from the opposing lateral sides with fingers of one hand.

As shown in FIGS. 10-15 , the upper side 205 of the container is performed straight and wider than the bottom part 208. The dispensing outlet of the product 104 is located on the tapering portion of the bottom part 208. Said constructive design allows easy extraction of the contents of the sealed part 203 of the container to be removed by simultaneous squeezing of the opposing lateral sides 206 and 207 of the wide upper part of the container towards each other with the fingers of one hand, resulting in the bottom part 208 of the container tears or moves apart in the place of the lower sealed strip 209 and the contents of the container are spilled out vertically downward smoothly and relatively evenly, and the product gets into the chosen place of the dispensing much more accurately.

As shown in the alternative embodiment in FIG. 13 , on the sealed strip 209 in the bottom part 208 a cut 210 can be performed in the lowermost part of the bottom 208 to indicate the dispensing outlet of the product 104. Said realization facilitates the process of the product extraction, and the tearing of the container in the lower part goes faster since the cut weakens the sealed strip strength.

FIGS. 14A, 14B, 14C, 14D show the container in which the front wall of the container 201 and the back wall of the container 202 are connected to each other forming the inner sealed cavity 203 with a longitudinal bottom.

FIG. 15 shows the container in which the front wall of the container 201 and the back wall of the container 202 are connected to each other forming the inner sealed cavity 203 in a form of a trapezoid with a narrow bottom.

FIG. 16 shows a container in which the front wall of the container 201 and the back wall of the container 202 are connected to each other forming the inner sealed cavity 203, a top of which is concave towards the bottom.

FIG. 17 shows the container in which the bottom part 208 additionally has a cross detail 211 of the sealed strip 209. Said cross detail 211 is intended to facilitate rupture of the container at its bottom part and the extraction of the contents by squeezing the single-serving disposable container from the opposing lateral sides with the fingers of one hand.

To produce the containers, according to the second variant of the invention, a vertical automatic packaging machine VZ-320 was used, originally intended for the production of containers with sugar (sticks) of the prior art with a packaging speed, according to the characteristics stated by the manufacturer, equal to 35-70 containers per minute, where the container is filled with granular contents and using a special press mold the sealed strip is formed along an entire perimeter of the container with a width of 3-5 mm and a trimming to intended shape is performed. To produce disposable single-serving containers according to the invention, a special press mold was made, and the packaging machine was reconfigured without changing its structural details. The maximum packaging speed for disposable single-serving containers according to the invention was 60-70 containers per minute. During the experiments, it was possible to easily extract the contents from the received container by simultaneous squeezing of the container in the upper part from the opposing lateral sides with the fingers of one hand towards each other. And the contents of the container have been dispensing vertically downward rapidly and relatively evenly.

The proposed invention is explained by examples.

EXAMPLE 1

In one of the preferred embodiments of the invention, to produce a single-serving disposable container for sugar with a capacity of 5 g product 104 a paper with a density of 45 g/m² laminated by polyethylene with a density of 13 g/m² was used. The mechanism of the opening of such a container is clearly explained in FIG. 18 . FIG. 18 shows that when pressure is applied to the lateral sides 106 and 107 of the container held by the phalanges of the thumb and index fingers, the container bottom part 108 tears in the place of the lower sealed strip, and sugar (product 104) under the pressure of the upper sugar layer and the force of gravity spills out vertically downward rapidly and precisely into the chosen place (for example, into a cup of coffee).

FIG. 19 shows the alternative mechanism of the opening. FIG. 19 shows that the container is gripped with the index finger and thumb from the front and the back, in the center or closer to its lower part, and the container is rubbed between the fingers, resulting in a rupture of the container bottom part 108 in the place of the lower sealed strip and sugar (product 104) under the pressure of the upper sugar layer and the force of gravity spills out vertically downward rapidly and precisely into the chosen place (for example, into a cup of coffee).

EXAMPLE 2

Example 2 is similar to Example 1 with the only difference in that the polymer film with a thickness of 25 microns was used for the production of the single-serving disposable container for sugar with a 5 g product capacity.

The examples and preferred embodiments disclose a single-serving disposable container for a granular product that can be conveniently opened with one hand. Usually, this is more convenient than using both hands and can be of particular importance when the user has only one free hand to manipulate the container, for example, when it is desired to add a product to the beverage while the other hand of the user is holding the beverage.

The proposed group of inventions is aimed at the creation of the improved container that:

-   -   can be opened with one hand;     -   the extraction of the inner contents occurs due to a smooth         rupture of the single-serving container in its bottom part,         which ensures even and much more accurate extraction of the         contents of the granular product, in comparison with         stick-packs, when opened with the fingers of one hand;     -   convenient one-handed extraction for people with reduced         mobility of the joints of the hands, for example, with         arthritis. When squeezing a single-serving disposable container         according to the invention, minimal flexion of the fingers is         required to extract the contents;     -   reliably protects the contents from moisture ingress, as it is         made either of paper with the polyethylene laminating layer or         of the polymer film;     -   connection of the container details along a perimeter is carried         out by pressing, resulting in the forming of the sealed strip,         thus preventing spontaneous dispensing of the contents from the         sealed part of the container;     -   depending on the capacity, it provides an economy of materials         for the production of a single-serving disposable container in         comparison with the production of stick-packs and standard         rectangular containers for sugar;     -   easily provided by means of dating or identification;     -   no glue is used to seal the contents of the container.

The proposed containers can be used for packaging various granular products such as sugar, salt, other comestibles, and non-comestible granular products, medicines, and materials.
